As mentioned in the getting started guide you much specify -march=armv4t when 
compiling for armv4t CPUs like the arm920t. Otherwise the linker may end up 
pulling in code that does not work on your CPU.

Check the permissions on the dynamic loader (/lib/ld-2.3.6.so). This must be 
executable to run dynamically linked executables (linux executables are 
normally dynamically linked).
